• Pick-up that emits a laser beam is used in this CD player section.
1. Cautionary instructions in handling the assy(Safety instructions)Optical pickupThe laser beam used in the pickup is classified as "class 2". Ex-posing your eyes or skin to the beam is harmful. Take care not todo so.
(Caution against static electricity and leakage voltage)Ground securely the work tables, tools, fixtures, soldering irons(including those made of ceramic) and measuring instrumentsused in the production lines and inspection departments thathandle loaders. The workers shall also be grounded.
(Cautionary instructions in handling)Do not touch the object lens when handling a loader, or the lenswill be stained, resulting in inadequate playability.There is no power supply protection circuit provided for this prod-uct or adjustment/inspection device. Short-circuiting may lead tofire or damage.Take care so as to protect from exposure to water, the entry ofmetallic pieces or dew condensation.In particular, a strong magnet adjacent to the pickup will not onlyget inoperative but can damage the pickup if a small metallicpiece, such as a screw or swarm, enters.The loader edge can cause injury if inadvertently handled.Do not touch a rotating disk, or injury may result.
This product is a precision device. Handle carefully.A shock or dropping will cause misalignment or destruction. If itshould occur, refer to clause 2.This product is so designed as to endure an initial shock equiva-lent to a drop from a height of approx. 90 cm under the packedcondition.After the initial shock, the resistivity will still remain at a level of50 to 60 G, but the mechanical robustness will weaken.Do not place in a dusty location.The entry and deposition of dirt into or on the pickup lens ormoving section will cause malfunction or degradation.
DVD MECHANISM REPLACEMENT
(Connectors)Do not connect or disconnect while power is on.Connecting or disconnecting signal wires or the main power cordwhen the power is on may destruct the unit or fixture.When connecting, push all the way in securely.An insufficient insertion may cause a bad contact, leading to anerroneous operation.Do not connect or disconnect roughly by an excessively strongforce, or a broken wire or bad contact may result.Semiconductors are connected. Do not touch connector termi-nals directly.If the worker is grounded, there is nothing to worry about staticelectricity, but the rust on the connector terminal surface causedby the touch may result in bad contact.
(Caution) Before disconnecting FFC cable, make it "SHORT" as shown left. After connecting FFC cable,make it "OPEN" as shown left.
(Power source)The power source need be good in quality (free from instanta-neous interruptions or noises).A low quality power source may well cause malfunction.
(Storage)Do not place or store in a dusty place or a place where dewcondensation is possible.The entry and deposition of dirt or dust into or on the pickup lensor moving section will cause malfunction or degradation.Also, dew condensation causes rust; the rust penetrate into theprecision part of a pickup, causing malfunction, or degrading theoptical quality of the internal lens and reflector, which also leadsto malfunction.

SERVICE MODE
B. How to enter Service Mode.You can enter Service Mode in any one of the following ways (1 to 3).
1. Using the buttons on the main unit
1-1. Dislay on "No Disc" by Function button.
1-2. Immediately (within one second) after pushing sound preset button both and buttons simultaneously,
push button.
A. Market / Region SETUPIn the initial condition for this model, Market and Region
information are undefined.
In the following cases, be sure to set up Market/Region.
1. When updating the system using CD-R
(Part code :0PRADC9695--A ).
2. When replacing a DVD substrate.
While Market/Region information are undefined, the message
"Region Undefined" is displayed on the screen.
NOTE: Even if the condition is not under 1 or 2 above, if the
message "Region Undefined" is displayed, be sure to set up
Market/Region.
2. Pushing the covered key located beneath Book Mark key on RB-
1500 or REM-S1500.
3. Simultaneously pushing both Shift key and ON SCREEN key on RB-TS780.

C. Setup Procedures1. Displaying SERVICE MODE screenDisplay Service Mode screen following the instructions "How to
enter Service Mode" above. Region 0 Market BackendVersion S31130A0Loader Version 17 Z09 Y03
Value
2. Displaying Internal Setup screenPush button within three seconds after operating the
Service Mode display.
On the Internal Setup screen shown on the right, set up Market
and Region.
3. Setting Market code
3.1. While a highlighted indicator is displayed on the right side
of the Market denotation, push numeric buttons on the
remote controller.
When you push wrong number , push CLEAR button.
(The indicator reset to "00")
Be sure to input by double figures.
Maket code of UK model is "02", and XE model is "03".
3.2. Specify the code of the model in accordance with the
Market/Region Setup Table above.
3.3 Once the desired code is displayed, push p button to
move the highlighted indicator to the Region input area.
4.2 Set up the region coder currently displayed on the set.
4.3 Once the desired number is displayed, push p button to
move the highlighted indicator to Exit area.

SERVICE MODE
D. IMPORTANT NOTE1. Once the "Market/Region" settings are written into EEPROM (IC801) on the DVD substrate, they cannot be reset.
(However, updating the system using CD-R enables you to make new settings.)
2. While the Internal Setup screen is displayed, pushing the Power button enables you to terminate the operations without
making any settings.
HOW TO LOAD SOFTWARE FOR MPEG P.W.BOARD
1. Power on, then open disk lid.
2. The function key of remote control is pushed and it is made DVD/CD mode.
3. It take on CD-ROM for UPDATE software to the tray, and disk lid close.
4. It is displayed on a screen as "Reading" and is displayed on LCD as "READING."
5. A screen will become noise-like if UPDATE is started.
Cautions) update is not ended even if rotation of a disk stops.
3. For the time being, tray open and FL display remain "UP DATING".
4. Loading of software will be completed, if update is started and about 60 seconds pass,
then the display of "update" of LCD will be "GOOD-BY" and disappears soon.
5.The disk for update is taken out.
6. Next, set up market code and region code by "SERVICE MODE"
CD-ROM part code is "0PRADC9695--A".
CAUTIONS FOR PWB OR IC ASSY EXCHANGEAfter an MAIN board(614 329 5570) or IC ASSY(410 507 6601) exchange should carry out loading of the software by thenewest CD-R, and should check operation.
CAUTIONS FM ANTENNA WIREThe knot is made so that FM antenna line may not enter during a set of a line. If it enters in a set of FM antenna line, There is adanger that a line will melt into the high-fever part in a set.Be careful of below at things at the time of disassembly of a set, and an assembly.At the time of disassembly of a setRemove thermal shrinkage tube, and disassemble a set after loosening the knot of a line.At the time of the assembly of a setMake a knot to the place distant from the end of a line 885mm or more, fix a knot to it by thermal shrinkage tube(parts code :614 330 9918 ULSUMITUBE-F2,D4.0), and a line should not enter it from a knot.
CAUTION : Regular type resistors and capacitors are not listed. To know those values, refer to the schematic diagram.Regular type resistors are less than 1/4 W carbon type and 0 ohm chip resistors.Regular type capacitors are less than 50 V and less than 1000 µF type of Ceramic type and Electrical type.

Input FunctionActive on the positive going edge to sample all inputs.Disables or enable device operation by masking or enablinall inputs except CLK, CKE and L(U)DQM.Masks system clock to freeze operation from the next clockcycle. CKE should be enable at least one cycle prior to nocommand. Disable input buffers for power down in standby.Row/column addresses are multiplexed on the same pin.Row address : RA0 to RA10, column address : CA0 to CA7Select bank to be activated during row address latchtime.Select bank for read/write during column address latch time.Latches row address on the positive going edge of the CLKwith RAS low. Enable row access & precharge.Latches column address on the positive going edge of theCLK with CAS low. Enable column access.Enable write operation and row precharge.Latches data in strting from CAS, WE active.Makes data output Hi-Z, t SHZ after the clock and masksthe output. Blocks data input when L(U)DQM active.Data inputs/outputs are multiplexed on the same pins.
Power and ground for theinput buffer and the core logic.Isolated power supply and ground for the output buffersto proxide improved noise immunity.This pin is recommended to be left no connection on thedevice.
